Cometic Head Gaskets
Cometic Head Gaskets Anyone have a set of Cometic head gaskets 4030 bore in stock or for sale??
Anyone running over 15lbs boost with GM MLS?
Last time (before my most recent rod problems) ran GM MLS with only 10 psi and a 100 shot with ARP head bolts and was leaking through 2 cylinders..
Going back together with ARP studs. But more PSI this time around..

i ran stock gaskets with arp studs to over 16psi many times. probably made 30+runs on them. i also ran 13psi and a 75shot a few times. i had head gasket problems untill i over torqued the head studs. i went 15ft-lbs over what the directions said to and had no more problems.

i have run the cometic and the gm mls to 20psi myself with pump gas/meth without problems with either....not that psi is the determining factor for how good a head gasket is...
